单选题How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone. The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection. The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. "It's kind of like having a dentist actually watch your brushing on a day-to-day basis," says Thomas Serval, the French inventor. The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. "We try to make it smart but also fun," Serval says. Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said "yes," but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed. The company says the Kolibree will go on sale this summer, for $ 99 to $ 199, depending on features. The U. S. is the first target market. Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

单选题It is not unusual for chief executives to collect millions of dollars a year in pay, stock options, and bonuses. In the last fifteen years, while executive remuneration rose, taxes in the highest income bosses went down. Millionaires are now common-place. Amiability is not a prerequisite for rising to the top, and there are a number of chief executive officers with legendary bad tempers. It is not the boss' job to worry about the well-being of his subordinates although the man with many enemies will be swept out more quickly in hard times; it is the company he worries about. His business savvy is supposed to be based on intimate knowledge of his company and the industry so he goes home nightly with a full briefcase. At the very top--and on the way up--executives are exceedingly dedicated. The American executive must be capable of enough small talk to get him through the, social part of his schedule, but he is probably not a highly cultured individual or an intellectual. Although his wife may be on the board of the symphony or opera, he himself" has little time for such pursuits. His reading may largely concern business and management, despite interests in other fields. Golf provides him with a sportive outlet that combines with some useful socializing. These days, he probably attempts some form of aerobic exercise to "keep the old heart in shape" and for the same reason goes easy on butter and alcohol, and substances thought to contribute to taking highly stressed executives out of the running. But his doctor's admonition to "take it easy" falls on deaf" ears. He likes to work. He knows there are younger men nipping at his heels. Corporate head-hunting, carried on by "executive search firms", is a growing industry. America has great faith in individual talent, and dynamic and aggressive executives are so in demand that companies regularly mid each other's managerial ranks.

单选题{{B}}Directions:{{/B}} There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the drastic experiment of Frederick H in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent. All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected. Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed. Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1,000 words which be can put into sentences, and at four his language differs from that of his parents in style rather than grammar. Recent evidence suggests that an infant is born with the capacity to speak. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways. But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's nonverbal signals is essential to the growth and development of language.

单选题People can be addicted to different things—e.g. alcohol, drugs, certain foods, or even television. People who have such addition are compulsive, i.e. they have a very powerful psychological need that they feel they must spend money. This compulsion, like most others, is irrational—impossible to explain reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending enormous amounts is actually greater than the pleasure that they get from the things they buy. There is special psychology of bargain hunting. To save money, of course, most people search for sales, low prices and discounts. Compulsive bargain hunters, however, often buy things they don"t need just only because they are cheap. They believe that they are helping their budgets, but they are really playing an exciting game: when they can buy something for less than other people, they feel that they are winners. Most people, experts claim, have two reasons for their behavior: a good reason for things that they do and the real one. Of course, it is not only scientists who understand the psychology of spending habits, but also business people. Stores, companies, and advertisers use psychology to increase business: they consider people"s needs for love, power, or influence, their basic value, their beliefs and opinions, and so on in their advertising and sales methods. Psychologists can often use a method called "behavior therapy" to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money.

单选题Excerpt 1: Sales of e-readers surged during the Christmas holiday season, according to a Pew Research Center report, which showed that the number of adults in the United States who owned tablets nearly doubled from mid-December to early January. Excerpt 2: Apple, based in Cupertino, California, controls 73 percent of the market, while Samsung Electronics Co., Sony Corp. and Toshiba Corp, are among companies making constant improvements on tablets Without bringing services that cut into the market share, Sarah Rotman Epps, an analyst at Forrester, said in the report. Excerpt 3: Under Square"s year-long pilot program, an iPad would be installed in the space where Taxi TVs currently sit, and the driver would have an iPhone to process credit-card payments. The technology would allow drivers to accept a passenger"s card at any point during the ride, then enter the amount later. The system charges drivers less in credit card transaction fees than the current rates. Excerpt 4: When Apple introduced the iPad tablet computer in 2010, it was doing what it likes to do best: creating a new category to dominate, as it had done with the iPod and iPhone. By the end of the year, the company had sold nearly 15 million iPads, generating about $9.5 billion in revenue. Just two years later, the chief executive of Apple, Timothy D. Cook, has a prediction: the day will come when tablet devices like the Apple iPad outsell traditional personal computers. Excerpt 5: Apple has made its first attempt to quantify how many American jobs can be credited to the sale of its iPads and other products, a group that includes the Apple engineers who design the devices and the drivers who deliver them-even the people who build the trucks that get them there. On Friday, the company published the results of a study it commissioned saying that it had "created or supported" 514,000 American jobs. The study is an effort to show that Apple"s benefit to the American job market goes far beyond the 47,000 people it directly employs here. Excerpt 6: People who read e-books on tablets like the iPad are realizing that while a book on a black- and-white Kindle is straightforward and immersive, a tablet offers a menu of distractions that can fragment the reading experience, or stop it in its tracks. E-mail lurks tantalizingly within reach. Looking up a tricky word or unknown fact in the book is easily accomplished through a quick Google search. And if a book starts to drag, giving up on it to stream a movie over Netflix or scroll through your Twitter feed is only a few taps away.
